I don't manage to upload file whose size is greater than 9MB, I get a connection aborted error.

I use PHP 4.0.4pl1, Win2000, IIS5 and IE 5.0 or NS 4.77 as browser.

In the php.ini I set memory_limit = 80M, upload_max_filesize= 80M

With small size file all works fine.

This is the script

Form:
<form method="post" action="software_add.php" enctype="multipart/form-data">
	<INPUT TYPE="hidden" name="MAX_FILE_SIZE" value="80000000">
	<input type=file name="file_software">
  <input type="submit">
</form>

Software_add.php:
<?
copy($file_software, "$DOCUMENT_ROOT\\software\\$file_software_name");
?>

Are you sure the script isn't getting a timeout?
ie. try putting set_time_limit(0); in beginning of that
script. 

Anyway, the HTTP upload code in PHP is not very suitable
for uploading very big files since it stores everything
in memory before writing it to disk.

(There already is another bug report open about that.)

Yes, it isn't a timeout problem, I've tried both set_time_limit(0) and the same in php.ini; the script crash immediately when I post the file.

I know that the file is stored in memory, but I set memory_limit = 80M so it should work. Why if the size is > 9MB (with a file size of 8MB still works fine) the script crash?

What is the post_max_size in your php.ini?

The http upload support has been rewritten in CVS now.
You can try the latest development build from 
http://www.php4win.com/ 
but make sure it's dated after 27th of October 2001.
(at the moment they don't have any builds there which have
the fix)

Also, there are some minor leaks still in the new code.
If you encounter such leaks, please send the shortest
possible code + html with which you can reproduce the leak
to php-dev@lists.php.net (or me) so we can get rid of these leaks. 

This fix will be in PHP 4.2.0.
